The front end of each sprinkler tip 24 is provided with the current stop valve 16.
It should be noted that at normal temperatures, solubility of the ammonia in water is about 400g/kg, it is seen that water energy absorbs well
The ammonia NH3 molecules dissociated in air.Therefore, the present invention is prevented by absorbing the ammonia of leakage effectively in the form of water spray
Chance burning things which may cause a fire disaster explodes after only the aerial content of ammonia reaches its LEL.
Easy leakage, the easy problem that set off an explosion that the present invention exists for existing ammonia compression refrigerating system, make full use of
Ammonia system carries water tank, and Computer Aided Design can in time find the ammonia detection alarm unit of ammonia leakage and prevent ammonia level exceeded
Water spray unit.
By taking compressor 1 and accessory region as an example, the ammonia detection alarm unit of present invention offer is provided and ammonia is prevented
The specific workflow of the exceeded water spray unit of Gas content:
Under normal circumstances, the ammonia in ammonia compression refrigeration unit is not leaked or the leak time loss of quantity is few, will not cause ammonia
The alarm triggering of gas detector 17, ammonia detection alarm unit is in quasi-operating status.When ammonia occur in compressor 1 and accessory
The leakage point of gas, when persistently leaking, the ammonia near it can gather, and ammonia level constantly rises, once reach preset alarm value
When (such as the 25% of preset security value), master controller in ammonia detection alarm unit will be triggered to user's (such as ammonia refrigeration
The administrative staff of compressibility) alarm is sent, by user.If ammonia level is more than or equal to default after constantly rising
Water spray value (such as the 50% of preset security value), then master controller in ammonia detection alarm unit can further to being connected
Water spray unit send water spray control signal, sprayed water by water spray unit, prevent potential safety hazard.For shown in Fig. 1
For ammonia compression refrigerating system, will control to open the stop valve 16 of fire pump 11 and the front end of sprinkler tip 24, so that water is from spilling
Sprinkler head 24 sprays, it is to avoid the ammonia level in air continues to raise and reach chance naked light blast after LEL;Now user
Can as early as possible take emergency measures, close ammonia compression refrigeration unit and cut off line related, forbid various ignition sources to enter alarm
Region, and take measures to reduce the economic loss stopped transport and being likely to result in by ammonia compression refrigeration unit.
Additionally, for the present invention, when condenser and accessory region, evaporator and accessory region and pipeline connect
When there is ammonia leakage in the place of connecing region, master controller (such as model of Siemens Company's production in ammonia detection alarm unit
By the Programmable Logic Controller of s7-200CPU224) water spray control signal will be accordingly sent to the water spray unit for connecting, by spraying water
Unit is sprayed water, and prevents potential safety hazard.
For the present invention, to accelerate absorption of the water to ammonia in air, each described sprinkler tip and the fire-fighting
Connecting line between water pump is by the evaporator 7 (such as by the back side of evaporator 7) in ammonia compression refrigeration unit so that water
Temperature declines, and improves solubility of the ammonia in water.
In sum, compared with prior art, a kind of ammonia with blast prophylactic function that the present invention is provided compresses system
Cooling system, it can efficiently reduce the harm that NH_3 leakage is likely to result in, and security performance is high, ensure that user's uses peace
Entirely, so as to promote the further genralrlization of ammonia compression refrigerating system to popularize, widely production application is conducive to, with great production
Practice significance.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
